AP PSYCHOLOGY

Detailed explanation-1: -Most females will start puberty when they’re 8 to 13 years old, and most males will start between 9 and 14. But it can also be normal to start earlier or later. Hormones from the brain trigger the start of puberty. Hormones are chemical messengers that tell the body what to do.

Detailed explanation-2: -Boys begin puberty sometime between the ages of 9 and 14. Boys hit puberty about two years later than girls. However, Black and Hispanic boys tend to enter puberty a bit earlier than white boys. If your son starts showing signs of puberty before age 9, it’s worth asking his pediatrician about these early changes.

Detailed explanation-3: -According to the National Institutes of Health, puberty usually begins in girls between 8 and 13 years of age, and in boys between 9 and 14 years of age. Puberty is considered to be early in boys before age 8 and girls before 9 years old. This is sometimes called “precocious puberty.”

Detailed explanation-4: -Puberty is the time in life when a boy or girl becomes sexually mature. It is a process that usually happens between ages 10 and 14 for girls and ages 12 and 16 for boys. It causes physical changes, and affects boys and girls differently.

Detailed explanation-5: -Boys can start puberty at a wide range of ages, with 95% starting between the ages of 9 and 14, so we consider puberty delayed when it has not started by age 14. The earliest sign of puberty in boys is enlargement of the testicles, followed by growth of the penis and pubic hair.
